The tangent secant theorem says
PR × PS = PQ²
4 × (4+5) = PQ²
36 = PQ²
PQ=6
Answer: 6
Answer:
≈ 12.65 Square units
Step-by-step explanation:
lateral area of a pyramid may be given by the formula;
L. A = l√((w/2)² + h²) + √((l/2)² +h²)
length = 2 , width = 2 and height = 3
= 2 √((2/2)² + 3²) + 2 √((2/2)² + 3²)
= 2 √10 + 2√10
= 4√10
= 12.649
≈ 12.65 Square units
The circumference of a circle equals to 2 x pi x radius.
To find the radius we can substitute the value of 37.7 in and use 3.14 as pi.
37.7 = 2 x 3.14 x radius
37.7 = 6.28 x radius
(377/10) x (100/628) = radius
1885/314=radius
The length of the radius is approximately 6 cm.
C. because the area of the square=17×17= 289. the area of the circle=17÷2= 8.5×8.5=72.25×3.14=226.865+289=515.865=515.9
